erncrrrcnrron'rorming'prt of Letters intent No. 687,419, dated November2e, 1901.

Application filed March 25, 1901. Serial No. 524,730. (No modell) To @ZZwhom t may concern.- Be it known that I, RICHARD BEAUMONT,

fof Kankakee, in the county of Kankakee and'` 'State of Illinois, haveinvented certain new series of water-drums s-upported within a shell'over a combustion-chamber.

The device consists in the matters hereinafter set forth, and moreparticularly pointed Aout in the appended claims.

In general terms a `device which embodies the principal features of myinvention comprises a combustion-chamber, an outer cylindrical shellrising therefrom, and a series of cylindrical water-drums supported inthe shell over the combustion-chamber, the upper of said drumssupporting a smoke-chamber and the remaining drums being suspended yfromthe upper drum in tandem within the shell.

In the drawings, Figure l is a view in vertical section of awater-heater embodying the salient features of my invention. Fig. 2 isaA View in cross-section through the heater on line 2 2 of Fig. l. Fig.3 is a view in crosssection through one of the drums, taken on line 3 3of Fig. l.

Referring to the drawings, A represents a combustionchamber of ordinarypattern. As shown herein, it is provided with the usual grate a andash-pit a and side walls a2, which extend upwardly above the grate, soas to form a circular chamber with Haring sides. Extending upwardly fromthe upper margin of said combustionchamber and supported thereon is acylindric metallic inclosure or` shell B. This may be inclosed, ifpreferred, in masonry setting C, as herein shown, or may be lagged outand jacketed. The upperend of said shell supports on its upper margin awater-drum D, formed of cast-iron, or built of sheet metal, ifpreferred. Said water-drum D is formed with flues and a deflector-plate,as hereinafter more fully described, and carries an upper smoke-chamberd', made, preferably, of sheet metal and adapted to lead the smoke andgases of combustion from the flues of the drum D to a suitablesmoke-pipe E. Obviously-said`smoke-chamber may be of any desired form.As herein illustrated, it is formed by a cylindrical side wall d2 and anupper end wall d3, the latter having an aperture adapted for connectionwith the smoke-pipeEintheusualmanner. Thedrum D, which is of lessdiameter than the shell B and is dependent therein, is formed by a flatupper plate d4, which extends over the upper margins of the shell B andis secured thereon at its margin d5, so as to form a tight joint,

a cylindrical side wall d6, depending from thev plate d4 within theshell B and of considerably less diameter than the internal diameter ofthe shell B, and by a horizontal bottom plate d?, secured to thelowermargin of the side wall d6. Passing through said drum are a plurality ofvertical flues F, said iiues being arranged symmetrically in said shellor drum and being formed with converging side walls d8,so as to be inform truncated cones. The upper plate d4 of said drum is provided withan upwardly-projecting boss or nipple d9,which is centrally locatedandiis provided with an aperture suitably screw-threaded or otherwisefitted for connection with a water-outlet pipe G, which extends upwardlytherefrom to the smoke-chamber d/ and into the smoke-pipe E, from whichit is led in any direction desired. A depending boss d10 is centrallylocated on the lower surface of the bottom plate C17 of the drum and islikewise provided with an aperture screw-threaded for pipeconnection,said aperture beingin approximate alinement with the apertureof the upper nipple d. Midway between the upper and lower end plates d4and @Z7 of the drum D is a horizontal deector-plate H, which issupported by resting on or being connected with the side walls d3 of theflues F. By this arrangement of the parts the detlector-plate H isinterposed in the line of flow between the upper and lower apertures ofthe bosses or nipples d and d10. Suspended from the drum D by means of aconnecting-pipe I, secured by screw-threads in the aperture 0f thedepending nipple d10, is a water-drum K, which is similar in the main tothe drum D, being provided with upper and lower horizontal walls IOO 'drum.

7c 7c', cylindrical side wall k2, and preferably equal in externaldiameter to the side wall d6 of the drum D, and ilues F', similar inshape to the llues F and equal in number. The upper horizontal end wallk projects beyond the side walls 7a2 a sufficient distance to form anannular horizontal flange k3, whose external diameter is slight-ly lessthan the internal diameter of the shell B, so as to afford a narrowpassage between the flange and the shell. The drum K is further providedwith an interior deilector-plate II', similar to the deflector I-I, andouter bosses or nipples kf h5, centrally apertu red and in triorlyscrew-threaded for connection with the connecting-pipe I and a dependentconnecting-pipe I. Said pipe I' serves as a connection and support for aseries of two or more drums K K2 de pendent therefrom, the intermediatedrums, as K', being similar in every respect to the drum K, and thelowest one, as K2, of the series having no deliector plate and having inplace of the lower boss in the center of'its bottom plate a side boss ornipple 76"', centrally apertured and screw-threaded for the reception ofa feed-water pipe L, which extends therefrom out through the wall of theshell D and the side of the furnace for convenient connection with anywater-supply. In mounting the drums it will be observed that theconnecting-pipes I, I', and I2 are so fitted that when the drumsarescrewed home thereon the ilues of each drum are staggered withrespect tothe flues of the adjacent drums.

The operation of the device is obvious. The products of combustion andthe heat arising from the combustion-chamber A are conducted by thewalls of the shell B to the lower drum K2, against which they impingeand are divided, a part passing upwardly through the converging walls ofthe lues F3 and a part passing up between the side walls of the drum andthe side walls of the shell B around the upper horizontal flange oftheThe currents from the flues strike against the bottom wall of the drumabove it owing to the staggered position of the fines and are divertedalong the bottom of the drum to the ues, through which they pass up toand against the bottom of the succeeding drum K'. The part of thecurrent passing around the side wall of the drum is partiallyarrested bythe horizontal flange thereof, so as to thoroughly heat the side walls,and then escapes around the flange and passes up to the next drum, whereit is again momentarily checked by the flange. Thus the heat-currentsfrom., the combustion-chamber are caused to pass over nearly the entiresurface of each drum until they finally reach the smoke-chamber d abovethe upper drum D,

from whence they escape through the smokepipe E. In this manner thegreater portion of the dru m-surfaces are heated by direct contact withthe hot gases. The funnel shape of the flues affords a comparativelylarge wallsurface, which, owing to its position with re'- gard to thecurrents of hot gases, is highly heated. Water is fed into the lowestdrum K2 through the pipe L. There it comes in Contact with the heatedbottom plate and the side of said drum and the flaring side walls of theilues F3 and thence passes upward through the connecting and supportingpipe I2 into the next drum K. Here it impinges against thedellector-plate H2, which causes it to flow outwardly around the wallsof the flues F2 and the side walls of the drum, so as to come in contactwith the heated surfaces thereof before it passes up through theconnecting-pipe I into the next drum, where it is again deflected by theplate H. By this means a thorough circulation of the water against thethoroughly-heated walls of the through the entire series of drums andreaches the discharge-pipe G.

An important advantage in this form of construction is in the method ofsupporting the drums inthe shell B. The drums hang entirely free fromthe shell B and are therefore independent therefrom and are notsubjected to any strain of internal expansion. Furthermore, they arevery easily mounted and dismounted for repairs or replacing the parts,it only being necessary to screw each drum home on its connectingcentral pipe. Any amount of heating-surface can be obtained by meremultiplication of the drums and proportionate increase in the size ofthe combustion chamber and shell B without the usual complicationarising in many forms of construction of water-heaters due to increaseof weight and the multiplication of supporting devices.

It will be understood that Ido not limit myself to the specific form ofconstruction herein shown, except as set forth in the appended claims.
